Who was Wilhelm Wundt and what did he do?
-In 1873 Wilhelm Wundt published the first book on psychology ‘Principles of Physiological Psychology’
-in 1879 opened the first psychology laboratory in Leipzig, Germany.
-He is often considered to be ‘the father of psychology’
- his approach became known as structuralism.
-established psychology as a science by using the scientific method
what is structuralism?
study of the structure of the human mind, by breaking down behaviours into their basic elements,
what are the three components of structuralism?
-Thoughts
-Images
-Sensations
What did Wundt use to investigate the human mind?
introspection
what is introspection?
A systematic experimental attempt to study the mind by breaking up conscious awareness into basic structures of thoughts, images and sensations
What were the two major assumptions Wundts new scientific approach was based on ?
-All behaviour is seen as being caused (determined)
-If behaviour is determined, then it should be possible to predict how human beings would behave in different conditions (predictability)
The scientific method refers to the use of investigative methods that are…
-Objective (factual)
-systematic (controlled)
-replicable (or standardised procedures)
evaluation of introspection
-Introspection relies primarily on non-observable responses and although participants can report conscious experiences, they are unable to comment on unconscious factors relating to their behaviour.
-Introspection produced data that was subjective (varied greatly from person to person), so it became very difficult to establish general principles.
Behaviourist approach
a way of explaining behaviour in terms of what is observable and in terms of learning.
what did the behaviourist approach reject?
introspection
key assumptions of the behaviourist approach
-We are born as “blank slates”
-All we have at birth is the capacity to learn
-All behaviour is learned from the environment
-Focus of the approach: observable behaviour
the behaviourist approach is only interested in studying behaviour that can be …
observed and measured
classical conditioning
learning by association and refers to the conditioning of reflexes and involves associating a new stimulus with an innate bodily reflex
Who demonstrated classical conditioning?
Pavlov
the formula for classical conditioning
UCS = UCR
Unconditioned stimulus = Unconditioned response
UCS + NS = UCR
Unconditioned stimulus + neutral stimulus = Unconditioned response
CS = CR
Conditioned stimulus = Conditioned response
the formula for classical conditioning (dog and bell example)
UCS = UCR
Food = salivation
UCS + NS = UCR
Food + bell = salivation
CS = CR
Bell = salivation
operant conditioning
A form of learning in which behaviour is shaped and maintained by its consequences.
name the three consequences (operant conditioning)
-Positive reinforcement
-Negative reinforcement
-Punishment.
what is positive reinforcement?
Involves receiving a reward when a certain behaviour is performed.
what is negative reinforcement?
Occurs when an animal/human avoids something unpleasant.The outcome is a positive experience, so they will do it again.
what was the skinner box experiment?
-showed how negative reinforcement worked
-placed a rat in his box and then subjected it to an unpleasant electric current which caused it some discomfort.
-As the rat moved about the box it would accidentally knock the lever. -electric current would be switched off.
-The rats quickly learned to go straight to the lever after a few times of being put in the box.
-The consequence of escaping the electric current ensured that they would repeat the action again and again.
Evaluation 1- well controlled research (behaviourist approach)
-strength
-its based on well controlled research
-behaviourists focused on the measurement of observable behaviour within highly controlled lab settings
-by breaking down behaviour into basic stimulus-response units, all other possible extraneous variables were removed allowing cause and effect relationships to be established
-e.g. skinner was able to clearly demonstrate how reinforcement influenced an animals behaviour
-suggests that behaviourist experiments have scientific credibility
Evaluation 2- Counterpoint of well controlled research (behaviourist approach)
-weakness
-behaviourists may have oversimplified the learning process
-behaviourists ignored an important influence on learning- that of human thought
-other approaches have drawn attention to the mental processes involved in learning
-suggests that learning is more complex than observable behaviour alone
evaluation 3- real world application ( behaviourist approach)
-strength
-principles of conditioning have been applied to real world behaviours
-operant conditioning has been used in institutions such as prisons and psychiatric wards
-they reward appropriate behaviour with tokens that can be exchanged for privileges
-this increases the value of the behaviourist approach because it has widespread application
